We ask this question to pair you with the best masks for your breathing style.

If you have a chronic obstruction (such as a deviated septum) or difficulty breathing through your nose regularly, you'll have a better therapy experience with a full face mask that delivers air to both the nose and mouth.

We ask this question to pair you with the best masks for your sleeping style.

Side sleepers will enjoy masks that are not too bulky in front of the face, swivel easily, and use thin or padded headgear on the side of the head/face.

Back sleepers are free to use whichever mask they prefer.

Stomach sleepers will benefit from low-profile masks that connect above the head, or have minimal bulk in front of the face.

Active sleepers are best suited to masks that are low-profile and swivel easily.

Some masks use multiple adjustable straps, which are sometimes located on top of the head, to provide a secure seal. If you might have difficulty reaching above your head, you'll likely have a better experience with a mask that has a single point of adjustment.
